1. SI Units International System of Units Helps to maintain consistency in reporting measurements Mass Volume Length

2. Mass Mass is measured in grams (g) – The standard unit of mass in the metric system is the gram. – Other units of mass and their equivalents in grams are as follows: 1000 milligrams (mg) = 1 g 100 centigrams (cg) = 1 g 10 decigrams (dg) = 1 g 1 hectogram (hg) = 100 g 1 kilogram (kg) = 1000 g

3. Mass is measured using a scale

4. Volume Volume is measured in liters (L) The standard unit of volume in the metric system is the liter – Other units of volume and their equivalents in liters are as follows: 1000 milliliters (mL) = 1 L 100 centiliters (cL) = 1 L 10 deciliters (dL) = 1 L 1 hectoliter (hL) = 100 L 1 kiloliter (kL) = 1000 L

5. Volume can also be measured in cubic centimeters 1 cm³ = 1 mL

6. Volume can be measured using graduated cylinders, beakers, Erlenmeyer flasks or pipettes

7. Length Length is measured in meters (m) The standard unit of length in the metric system is the meter – Other units of length and their equivalents in meters are as follows: 1000 millimeters (mm) = 1 m 100 centimeters (cm) = 1 m 10 decimeters (dm) = 1 m 1 hectometer (hm) = 100 m 1 kilometer (km) = 1000 m

8. Length can be measured with a meter stick or ruler
